Novel genetic variants of HLA gene associated with Thai Behcet's disease (BD) patients using next generation sequencing technology. Sci Rep 2024; 14:7967. [PMID: 38575661 PMCID: PMC10995258 DOI: 10.1038/s41598-024-58254-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Accepted: 03/27/2024] [Indexed: 04/06/2024] Open
Abstract
Behçet's disease (BD) manifests as an autoimmune disorder featuring recurrent ulcers and multi-organ involvement, influenced by genetic factors associated with both HLA and non-HLA genes, including TNF-α and ERAP1. The study investigated the susceptible alleles of both Class I and II molecules of the HLA gene in 56 Thai BD patients and 192 healthy controls through next-generation sequencing using a PacBio kit. The study assessed 56 BD patients, primarily females (58.9%), revealing diverse manifestations including ocular (41.1%), vascular (35.7%), skin (55.4%), CNS (5.4%), and GI system (10.7%) involvement. This study found associations between BD and HLA-A*26:01:01 (OR 3.285, 95% CI 1.135-9.504, P-value 0.028), HLA-B*39:01:01 (OR 6.176, 95% CI 1.428-26.712, P-value 0.015), HLA-B*51:01:01 (OR 3.033, 95% CI 1.135-8.103, P-value 0.027), HLA-B*51:01:02 (OR 6.176, 95% CI 1.428-26.712, P-value 0.015), HLA-C*14:02:01 (OR 3.485, 95% CI 1.339-9.065, P-value 0.01), HLA-DRB1*14:54:01 (OR 1.924, 95% CI 1.051-3.522, P-value 0.034), and HLA-DQB1*05:03:01 (OR 3.00, 95% CI 1.323-6.798, P-value 0.008). However, after Bonferroni correction none of these alleles were found to be associated with BD. In haplotype analysis, we found a strong linkage disequilibrium in HLA-B*51:01:01, HLA-C*14:02:01 (P-value 0.0, Pc-value 0.02). Regarding the phenotype, a significant association was found between HLA-DRB1*14:54:01 (OR 11.67, 95% CI 2.86-47.57, P-value 0.001) and BD with ocular involvement, apart from this, no distinct phenotype-HLA association was documented. In summary, our study identifies specific HLA associations in BD. Although limited by a small sample size, we acknowledge the need for further investigation into HLA relationships with CNS, GI, and neurological phenotypes in the Thai population.

Abstract
Autoimmune uveitis (AU) is a severe disorder causing poor vision and blindness. However, the cellular dynamics and pathogenic mechanisms underlying retinal injury in uveitis remain unclear. In this study, single-cell RNA sequencing of the retina and cervical draining lymph nodes in experimental autoimmune uveitis mice was conducted to identify the cellular spatiotemporal dynamics and upregulation of the glycolysis-related gene LDHA. Suppression of LDHA can rescue the imbalance of T effector (Teff) cells/T regulator (Treg) cells under inflammation via downregulation of the glycolysis-PI3K signaling circuit and inhibition of the migration of CXCR4+ Teff cells towards retinal tissue. Furthermore, LDHA and CXCR4 are upregulated in the peripheral blood mononuclear cells of Vogt-Koyanagi-Harada patients. The LDHA inhibitor suppresses CD4+ T cell proliferation in humans. Therefore, our data indicate that the autoimmune environment of uveitis regulates Teff cell accumulation in the retina via glycolysis-associated LDHA. Modulation of this target may provide a novel therapeutic strategy for treating AU.

Abstract
Behçet's disease (BD) is an autoimmune disease characterized by multisystemic variable-vessel vasculitis and oral, genital, and intestinal ulcers. Neurological involvement or "Neuro-Behçet" (NB) manifests due to parenchymal inflammation. We present the case of a 21-year-old male with a five-year-old history of intermittent chronic oral and genital ulcers who presented with headache, right hemiparesis, progressive loss of visual acuity, and a thalamic tumor-like lesion on magnetic resonance imaging (MRI). A brain biopsy showed multiple perivascular infarcts associated with vasculitis affecting arterioles, venules, and capillaries.

Abstract
IL-33 is a relatively new member of the IL-1 cytokine family, which plays a unique role in autoimmune diseases, particularly some oral diseases dominated by immune factors. The IL-33/ST2 axis is the main pathway by which IL-33 signals affect downstream cells to produce an inflammatory response or tissue repair. As a newly discovered pro-inflammatory cytokine, IL-33 can participate in the pathogenesis of autoimmune oral diseases such as Sjogren's syndrome and Behcet's disease. Moreover, the IL-33/ST2 axis also recruits and activates mast cells in periodontitis, producing inflammatory chemokines and mediating gingival inflammation and alveolar bone destruction. Interestingly, the high expression of IL-33 in the alveolar bone, which exhibits anti-osteoclast effects under appropriate mechanical loading, also confirms its dual role of destruction and repair in an immune-mediated periodontal environment. This study reviewed the biological effects of IL-33 in autoimmune oral diseases, periodontitis and periodontal bone metabolism, and elaborated its potential role and impact as a disease enhancer or a repair factor.

Abstract
PURPOSE OF REVIEW Provide a framework for recognizing key symptoms and clinical findings in patients with autoimmune inflammatory eye disease. RECENT FINDINGS The most common manifestations of autoimmune inflammatory eye disease are episcleritis, scleritis, uveitis (anterior, intermediate, posterior, and panuveitis), and keratoconjunctivitis sicca. Etiologies can be idiopathic or in association with a systemic autoimmune condition. Referral of patients who may have scleritis is critical for patients presenting with red eyes. Referral of patients who may have uveitis is critical for patients presenting often with floaters and vision complaints. Attention should also be directed to aspects of the history that might suggest a diagnosis of a systemic autoimmune condition, immunosuppression, drug-induced uveitis, or the possibility of a masquerade condition. Infectious etiologies should be ruled out in all cases. Patients with autoimmune inflammatory eye disease may present with ocular or systemic symptoms alone, or in combination. Collaboration with ophthalmologists and other relevant specialists is vital to optimal long-term medical care.

Abstract
Noninfectious posterior uveitis (NPU) comprises a heterogeneous group of vision-threatening, immune-mediated ocular and systemic diseases. It is predominantly bilateral and recurrent and, if not treated properly, leads to severe tissue damage that threatens the eyesight. In industrialized countries ca. 10-20% of all cases of blindness are caused by NPU. An NPU can occur at any age but is most common between the ages of 20 and 50 years. Laboratory diagnostic and imaging procedures enable an increasingly better differentiation of the disease spectrum. This makes it possible to better assess the course and prognosis of individual disease entities. An increasing repertoire of systemic and intravitreal forms of treatment has already led to more favorable long-term treatment outcomes. It can be expected that further progress can be achieved with better knowledge of the pathophysiology of the different clinical disorders and appropriate, targeted treatment.

Abstract
An array of retinochoroid imaging modalities aid in comprehensive evaluation of the immunopathological changes in the retina and choroid, forming the core component for the diagnosis and management of inflammatory disorders such as uveitis. The recent technological breakthroughs have led to the development of imaging platforms that can evaluate the layers of retina and choroid and the structural and functional alteration in these tissues. Ophthalmologists heavily rely on imaging modalities such as dye-based angiographies (fluorescein angiography and indocyanine green angiography), optical coherence tomography, fundus autofluorescence, as well as dye-less angiography such as optical coherence tomography angiograph,y for establishing a precise diagnosis and understanding the pathophysiology of the diseases. Furthermore, these tools are now being deployed with a 'multimodal' approach for swift and accurate diagnosis. In this comprehensive review, we outline the imaging platforms used for evaluation of posterior uveitis and discuss the organized, algorithmic approach for the assessment of the disorders. Additionally, we provide an insight into disease-specific characteristic pathological changes and the established strategies to rule out disorders with overlapping features on imaging.

Abstract
Behçet's disease is a rare and poorly understood vasculitis affecting blood vessels of all types and sizes. Uveitis and oral and genital ulcers represent the typical clinical triad. Populations along the ancient trading route connecting the Mediterranean basin with the Middle and Far East are most affected. Up to a quarter of the cases has a pediatric onset, typically around puberty. The aim of the treatment is early intervention to control inflammation, with symptom relief and prevention of relapses, damage, and complications. The heterogeneous clinical presentation often requires a multidisciplinary and tailored approach. Ocular, neurological, gastrointestinal, and vascular involvement is associated with a worse prognosis and needs more aggressive treatments. In young patients with expected prolonged disease, treatment should also focus on preventive measures and lifestyle advice. In recent years, the pharmacological armamentarium has grown progressively, although only a limited number of drugs are currently authorized for pediatric use. Most evidence for these drugs still derives from adult studies and experience; these are prescribed as off-label medications and are only available as adult formulations. Corticosteroids frequently represent the mainstay for the management of the initial acute phases, but their potential serious adverse effects limit their use to short periods. Different conventional disease-modifying anti-rheumatic drugs have long been used. Many other biologic drugs targeting different cytokines such as interleukin-1, interleukin-6, and interleukin-17 and treatments with small molecules including the phosphodiesterase 4 and Janus kinase inhibitors are emerging as novel promising therapeutic agents. In recent years, a growing interest has developed around anti-tumor necrosis factor agents that have often proven to be effective in severe cases, especially in those with a gastrointestinal and ocular involvement.
